Struggling to understand normal toddler behaviour as a first time mum. Help.

My son is almost 2 years old next week. His speech is excellent, his motor and fine skills are amazing. He honestly surprises me everyday at how great he is. He is a very curious child and loves solving problems. He loves singing and dancing and knows all the lyrics to sooo many songs. Hes very affectionate, he says I love you mummy and daddy everyday. When he hurts another person/kid he says sorry. He’s compassionate. Hes pretty good at following instructions eg if i say wait for mummy, he will wait. He loves climbing and jumping. He’s very happy when he’s jumping on the bed or just anywhere really. He runs a lot. He loves to take my hand and says ‘come on mummy’ and the takes me somewhere then communicates what he wants eg he’ll open the fridge and say I want banana or yoghurt or apple. Ofcourse as a 2 years old he throws tantrums occasionally and test boundaries. He also occasionally walk backwards, spin, walk on his top toes and flap his hands often. Its not majority of the time. Is this normal toddler behaviour? Am I overthinking? Am I being silly? Being a first time mum is so challenging. To me he’s thriving but sometimes I do get anxious about some developmental issues.
